Abstract

Modified polyisocyanates with biuret structure containing terminal urethane groups and having general formula:where R, is an aliphatic, cycloaliphatic or aliphatic-cycloaliphatic radical, simple or substituted, and R<sub>2</sub> can have the same meanings as R, or be the radical R<sub>3</sub>(OC<sub>n</sub>H<sub>2n</sub>)<sub>x</sub>-.Process for the preparation of modified polyisocyanates having biuret structure containing terminal urethane groups having general formula (l) consisting in reacting an organic diisocyanate with water or with a compound splitting off water, in the presence of a compatibilizing agent having a hydrogen atom reactive towards the isocyanate group, as it can be determined by Zerewitinoff's method.
